range upon the source of fluctuating steam supply. In this Way l am enabled, while maintaining only such variation of pressure as is desirable on the source of fluctuating steam flow, to increase the variations of pressure within the regenerator, and thus e11- large its capacity for supplying steam dur-' ii'igperiods in which the supply to the regenerative apparatus is small or shut off.

ln such installations as have heretofore been made the back-pressure on the interinittently-acting engine has had practically a fixed relation to the pressure in the steamspace of the steam regenerator, so that the back pressure on the primary engine has the saine range as `the pressure of the regenerated steam. By my invention. l adjust the difference of pressure between the steamspace of the regenerative apparatus and the source for supplying steam to said .apparatus according to the pressure of steam within thc-regenerative apparatus, increasing this pressure difference when the steampressure in the regenerative apparatus falls below a certain point. This makes available a range of pressure within the regenerative apparatus which heretofore was impracticable to employ, because it is undesirable for the pressure of the source to go substantially below atmospheric pressure, so that in previous apparatus this factor fixed the minimumfor the pressure on the secondary side of the regenerator. More specifically, l have provided regenerative apparatus having two ste-ani passages leading from the source of supply, one of these passages leads the n steam a considerable depth below a body of water within the regenerative apparatus,

`while the other ieads the steam to a point under water at considerably less depth or "head By opening and closing thelast nien- 'tioiied passageaceording as the steam-preegenerative apparatus so that when the pressure is low within thc regen@ ative apparatus there 1s a relatively large pressure-drop in the steam before reaching the steam- 'space therein, while if the pressure is relatively high within the regenerative apparatus there is a relatively small pressuredrop of the steam before it reaches the steam-space.

The drawing accompanying this specification illustrates in diagrammatic manner a system embodying one specific form of my invention.

l a source of iiuctuating steam-How, as for example, an intermittently-acting engine supplying widely and rapidly fluctuating exhaust steam. 2 is a passage for this steam. 3 is a regenerator supplied by this steam. 4 is a passage leading therefrom to carry the regenerated steam to its point of use.

5 is, for example, a steam turbine communicating with condenser tl. The regenerator is supplied with a relief valve 7 which llines the maximum pressure permitted within the regenerator and therefore the maximum backpressure permitted on the source 8 is piping leading from the supply pipe 2 to the regenerator and located therein at a considerable depth within the body of water 9 in the regenerator. The pipe 8 within the rcgenerator is supplied with numerous outlets 10, as is well understood in the art, to cause the steam to be divided as it enters the water and to get into intimate contact therewith and to promote circulation thereof. 11 is a second pipe similarly entering the regenerator and provided with similar openings l0, but this pipe is, as shown, located within the regenerator at a higher level in the Water.

12 is a valve controlling the opening and closure of piping 11, this valve being controlled by the movement of diaphragm 13. which is forced upwardly by the pressure of steani within the regenerator, the regenera# tor being connected in the space below the diaphragm by the pipe la. The pressure necessary to raise the diaphragm may be adjusted by varying' the position of the weight i5 upon the lever iti'through which `this intermittenti actino engine Wiis not substantially interfeie Withlts eiicieni; operation inwhich case thel 'eiiei valve 7 iuay be sef` "to open at a presume oi' three pounfis, At this p'essuie of three. pounds witl'iiiu the ,regenerator the back-pressuie upon Jdue source would only be. a inaction' of pound due to the low pressureircquie 'io force iiiel steam through a email dept-i1 o1 water through t Le openings I0 of the pipeii, che
